Runaway Bundesliga leaders Bayern Munich had their 20-match unbeaten run in all competitions ended at Hoffenheim on Tuesday as striker Andrej Kramaric's winner sealed the hosts' 1-0 victory.

Bayern's run came to an end a week before their mouth-watering Champions League home leg quarterfinal against Real Madrid.

This was Bayern's first loss since going down 3-2 at Russia's Rostov in a Champions League group game last November.

It was also only their second defeat in 27 German league games having also stumbled at Borussia Dortmund.

Second-placed RB Leipzig can now trim Bayern's massive lead to 10 points if they win at Mainz on Wednesday.

With a busy run of fixtures approaching, Bayern coach Carlo Ancelotti rotated his squad, but still started with 10 internationals.
